This tendency to backlash has been a very 4o objectionable difiiculty which presents itself in all casting operations, particularly so far as amateur fishermen are concerned, and considerable casting technique and thumbing skill, not to mention the proper use of the drag, is required in order to overcome this tendency to backlash on the part of the ordinary fishing line.

It has been found that the line of this invention will not backlash under practically all conditions and the theory is that this is due, at least in part, to the tubular construction which adds a certain amount of lineal rigidity and also resists any tendency to flatten out into a ribbonlike form. v Additionally, the tubular construction or circular cross section of the line of this invention will present, under practically all circum- In Figure 5 :the line. lfi is shown .asaappliedito will resist the for casting purposes, casts up to fifty percent longer can be made with the same equipment and others under the stances. a limited surface of frictional contact with other elements, there being practically a linear contact due to the circular structure, which is obviously less than any planar contact which would result from a line which is flattened on one or more surfaces or which presents a ribbon-like cross section.

the line in this spin casting operation will be resisted to a considerable extentby the tubular construction, and as the tube is imparted, .the

braided tubular contour will act to re'movethe' twistas the line is rewound upon the spool of the reel. l.

"The tubular construction of this line can be supplemented by a core which may comprise either a single filament or a plurality of filaments.

- The tubular construction is not necessarily always circular in cross section but may be elliptical and, in some cases, the tube may be flattened into practically a ribbon with substantially no inner space.

While the structure ed for a fishing line, the same can be employed for other purposes, such as strings for tennis and badminton rackets and in any other environment where this tubular construction, either hollow or reinforced with a core, isfound expedient.

The line, when used for fishing purposes, will not birdnest on the reel,'wil1 resist kinking and tangling, and when used with the spinning reel tendency to twist. When employed the line will wear approximately twice as longas same conditions. When made of material which is translucent and with substantially no outstanding color, it will be found to be almost invisible in or on the water, this, of course, being a distinct advantage I for fishing purposes.

' When used as a string or gut'for=tennis and badminton rackets, the fact that; the line is braided as distinguished from a single filament, will provide a better grip on the surface of the ball or bird, thereby enabling greateraccuracy J employed. 1

hereof is primarily intend- It will be evident that herein is provided a com pletely new fishing line which, by virtue of its inherent resistance to tangling, twisting, overrunning and backlashing, will provide a boon to fishermen, particularly amateurs who, by the use of this new line, will be able to make longer and more accurate casts without the ever present danger of snarling, twisting and tangling their lines, eitheron the reel or during the cast. 10

e The plurality of single filament strands braided into the tubular construction imparts arigidity and solidarity of structure whereby buckling,

twisting and flattening is almost completely eliminated, even under the most adverse conditions of use. No additional coating or lacquering is necessary and the-filaments being preferably of nylon, will act even more consistently when wet, thereby imparting a further advantage.

I am'aware that many changes may be made and numerous details of construction varied throughout a wide range without departing from theprinciples of this invention, and I, therefore,

do not purpose limiting the patent granted hereon otherwise than as necessitated by the prior art.

- I claim as my invention:

' 1. A fishing line comprising a coreless tubular braided structure, the braiding composed of a plurality-of filaments arranged in groups of two. or more in parallel untwisted, relationship and braided in'fours or multiples thereof.

2. A fishing line comprising a coreless tubular structure composed of nylon monofilaments of circular cross-section braided in fours or multiples thereof DAVID LIPPEY.
